This research study will test the effects of CHRP, a community-friendly risk reduction intervention, which is based on the Information-Motivation-Behavioral Skills model of health behavior change (IMB; Fisher & Fisher, 1992), and, thus, is designed to enhance knowledge, motivation, and behavior skills for reducing drug- and sex-related HIV risk behaviors. Outcomes assessed will include urine toxicology screens, self-reported HIV drug- and sex-related HIV risk behavior, HIV/AIDS knowledge, risk reduction motivation, and risk reduction behavioral skills.
